Honda Motor Co on Saturday praised an agreement to end a labor dispute at U.S. West Coast ports but said shipping delays will cost the company about 25,000 vehicles this month. Honda had been using air shipments from Japan to get some parts to its North American assembly lines and company spokesman Mark Morrison said it would continue doing so while port operations are ramped back up. Honda factories in Indiana and Canada will be operating at lower production levels through March 2, he said.
